Odd error starting happening...

All of a sudden I'm getting an error every time I edit a VI's icon (LV 2013):

Clicking OK to that and several similar errors (all "Could not load front panel") eventually leads to the icon editor properly opening but dismissing 5 error messages every time I edit an icon is going to get old real quick...

Any ideas on what could be causing this (I havent changed the icon editor packed library)?

If you haven't modified the Icon Editor, then my only ideas are to (1) repair your LabVIEW installation (in case any of the source files somehow got corrupted), or (2) rename your LabVIEW.ini file to LabVIEW.bak and restart LabVIEW to see if there are any errant entries in your INI file that would cause problems.

On the system that works, I could open the lvlibp without errors. On the other PC I get some errors:

I just checked on a system running LabVIEW 2013 SP1 and did not have any issues.

resource\plugins\lv_icon.lvlibp:

resource\DOMUserDefRef.dll (including "Details" page for version info as well):

Since, I am using a german windows, the dialogs are in german. But I think, the needed information is readable ;-)

I have an idea that it has something to do with certificates, because I have a similar problem when loading the NI OPC Server DLLs. (DLLs could not be loaded due to a "certification validation failure")
